Mixer and high-temperature flue gas treatment device with same

Abstract

The invention provides a mixer and a high-temperature flue gas treatment device with the same. The mixer comprises a shell and an isolation column, wherein a first gas inlet connected with a first gassource is formed in the bottom of the shell, a gas outlet is formed in the top of the shell, the isolation column is of a vertically-through hollow structure, one end of the isolation column penetrates through the shell and extends into the shell, a second gas inlet connected with a second gas source is formed in the other end of the isolation column, a plurality of through holes are formed in the isolation column located in the shell, a partition plate spirally wound around the isolation column is arranged in the shell, the inner end of the partition plate is in sealed connection with the isolation column, the outer end of the partition plate is in sealed connection with the inner wall of the shell, the partition plate divides the interior of the shell to form a spiral runner, the bottomend of the spiral runner communicates with the gas inlet, and the top end of the spiral runner communicates with the gas outlet. The contact area and the contact time of the first gas and the secondgas can be effectively increased, so that the second gas is in full contact with the first gas.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to a mixer and a high-temperature flue gas treatment device having the same. Background technique [0002] Magnesia-carbon bricks need to be added with phenolic resin as a binder during the production process, and during the drying process of magnesia-carbon bricks, some formaldehyde and phenol gases will volatilize into the air when the phenolic resin is cured, and then discharged out of the furnace along with it, polluting the environment. At present, the ozone ions produced by ultraviolet radiation are generally used to oxidize phenol and formaldehyde, but the amount of ozone produced by UV photolysis is very small, and the flue gas needs to be cooled during the UV photolysis process. The temperature of the flue gas generated is about 80°C, while the allowable range of the UV photolysis working temperature is below 40°C, and the flue gas discharge per hour needs a l...

Problems solved by technology

[0002] Magnesia-carbon bricks need to be added with phenolic resin as a binder during the production process, and during the drying process of magnesia-carbon bricks, some formaldehyde and phenol gases will volatilize into the air when the phenolic resin solidifies, and then discharge them outside the furnace, polluting the environment

At present, the ozone ions produced by ultraviolet radiation are generally used to oxidize phenol and formaldehyde, but the amount of ozone produced by UV photolysis is very small, and the flue gas needs to be cooled during the UV photolysis process. The temperature of the flue gas generated is about 80°C, while the allowable range of the UV photolysis working temperature is below 40°C, and the flue gas discharge per hour needs a large amount of cooling water when the flue gas discharge is nearly 10,000 cubic meters. When the flue gas contacts with water, a large amount of harmful gas Dissolved in water, if it is discharged, it will cause secondary pollution, if it is disposed of, it will increase a lot of production costs and cause unnecessary waste
